Title:
  Cloud image doesn't call resolvconf but writes a file at
  /etc/resolv.conf, causing resolvconf to complain

Status in Official Ubuntu Images on EC2:
  New
Status in Ubuntu:
  Fix Released
Status in “resolvconf” package in Ubuntu:
  Invalid

Bug description:
  Three days ago I lauched an EC2 Ubuntu Precise micro instance on
  Amazon Web Service. AMI: ubuntu/images/ebs/ubuntu-
  precise-12.04-i386-server-20120424 (ami-e7e8d393)

  This is my very first server experience so I'm going slow and reading
  and observing the system. During this three days I didn't install any
  new packages other than appyling four batches of updates. Some of them
  were security updates, some were not; some were kernel updates, some
  were not. My var/log/apt/history.log is attached.

  As a result:

  # uname -a
  Linux [some-internal-IP] 3.2.0-24-virtual #38-Ubuntu SMP Tue May 1 17:00:51 UTC 2012 i686 i686 i386 GNU/Linux

  If it might be useful:

  # ls -l /etc/resolv.conf
  -r--r--r-- 1 root root 91 May 23 09:59 /etc/resolv.conf

  # cat /etc/resolv.conf
  domain eu-west-1.compute.internal
  search eu-west-1.compute.internal
  nameserver 172.16.0.23

  I didn't do any configuration to the default system of any kind by
  myself. Up till now I just play with the basic commands such as
  whoami, top, ls, cd etc. and to observe the update/upgrade processes.

  As you can see from the attached file, my fourh and last upgrade is
  from resolvconf 1.63ubuntu11 to resolvconf 1.63ubuntu14 and the
  upgrade resulted with the error: "resolvconf: Error: /etc/resolv.conf
  isn't a symlink, not doing anything." What I get from connection up to
  that error is attached.

  I searched some on the Web and figured out that issues having
  something to do with the error "/etc/resolv.conf isn't a symlink, not
  doing anything" is being experienced for Ubuntu for years. The causes
  for all of them might not be the same but seems thet have to have
  something in common. I'm not an expert on such things. Some places on
  the Web for such discussions:
  http://ubuntuforums.org/showthread.php?t=1193585 ,
  http://askubuntu.com/questions/137037/network-manager-not-populating-
  resolv-conf , http://eric-b.net/?p=71 . There are discussions on
  Lauchpad as well: Bug #922677 is an example. Bug #324233 (with 3
  duplicates) sounds more alarming with what Thomas Hood (jdthood) wrote
  on 2011-12-03 at the end of his long comment with a patch: "Who am I?
  I am one of the maintainers of resolvconf in Debian. I would prefer to
  leave this work up to Ubuntu folks, but these issues have been left
  unresolved for years. Something has to be done."

  On a server installation such as EC2, with no extra package installed
  other than offical updates, with no personal configuration -all being
  the defaults- a bug known for years, for such a critical component for
  a server -again- surfaces up. Does it make sense?

  I'm not adding any more files, not adding the files the original
  reporter had attched as well because I don't know what you need. If
  you'll ask me for more files outputs, I can send them.

  I don't suppose so but if this a very interesting, atypical situation
  calling for deep investigation, I can give the control of the EC2
  instance for some time to a friend with reputation dealing with such
  issues. The instance is free of charge for 1 year and includes nothing
  except its default being. I can terminate it and launch a new one any
  time.

  Until I hear something from you here, I won't do anything, any update
  or so to that system for 2-3 days. ıf I can not hear something soon
  maybe I'll terminate it and can't answer probable questions anymore.

  Regards.

  PS: On the system in question, I can already view Web pages via w3m,
  if it means something in some way.
